  • the functional surface body which can be made in one piece or from several individual components, provides a surface with its functional surface that fulfils an intended function, e.g. a fastening function and/or a sealing function.
  • the functional surface can be used to attach the functional surface body and thus the box housing body, to the base section of which the functional surface body is fixed, to a wall on the building side, as mentioned above in the sanitary case, e.g. a side, ceiling or floor wall of a bathroom, a shower room, a toilet room, another sanitary room, a kitchen, etc.
  • the functional surface body can be releasably fixed to the base section at different axial heights of its functional surface, whereby the functional surface can be variably provided at an axial height that is optimal for the respective application in order to fulfil its intended function, e.g. in order to provide a fastening surface at the relevant axial level for fastening the connection box unit or its box housing body to a building-side wall surface and/or a sealing surface for sealing the connection box unit against a building-side wall surface.
  • the user can use the actuation interface to move the connecting body between the release position and the fixing position, thereby fixing the functional surface body to the base section of the box housing body or releasing it again for release.
  • the actuation interface is designed to be actuated by the user, e.g. for tool-free actuation or using an actuation tool and an associated tool interface profile on the actuation interface.
  • sanitary wall-mounted connection box units are known in which the functional surface body is supported by a plurality of mounting flanges which are formed on the base section in a bottom area thereof, projecting radially outwards and have fastening eyes, with the help of which the box housing body can be fastened to the bottom of a recess in a wall.
  • the patent documents EP 1 006 244 B1 and EP 2 636 803 B1 as well as the disclosure documents DE 10 2004 060 744 A1 and WO 2017/091839 A1 disclose corresponding designs as sanitary wall-mounted connection box units, whereby the latter publication also discloses the possibility of designing as an electrical wall-mounted connection box unit.
  • Generic wall-mounted connection box units ie those of the type mentioned at the beginning, differ from these in their ability to detachably fix the functional surface body to the base section at different axial heights of the functional surface.
  • EP 1 382 757 B1 discloses related sanitary wall-mounted connection box units in which the functional surface body is a closed ring body which acts as a fastening flange surrounding the sleeve section of the box housing body in a ring shape and can be fixed to the sleeve section at different axial heights by means of a screw or bayonet connection or is provided with axially protruding, dowel-like projections which can be inserted into fastening eyes which protrude radially from the base section at its bottom area and can be locked to these at different axial heights.
  • the disclosure document DE 10 2004 060 744 A1 discloses another related sanitary wall-mounted connection box unit, in which a sealing tab acts as the functional surface body, which is formed on the sleeve section in the region of the open front end so as to protrude radially outwards and provides a sealing surface for sealing the sanitary component receiving space against the building wall, wherein the sleeve section of the box housing body is formed by a bellows, by means of which the sealing tab can be placed at a variable axial height relative to the base section of the box housing body.
  • the disclosure document DE 10 2017 100 707 A1 discloses a generic sanitary wall-mounted connection box unit in which a one-piece fastening frame surrounding the sleeve section acts as the functional surface body and the Connecting device as a connecting body comprising spring tongues projecting axially from the fastening frame as well as associated securing clips and as a connecting structure locking areas on the outer circumference of the base section of the box housing body that detachably interact with the spring tongues.
  • the fastening frame is pushed over the sleeve section of the box housing body until its spring tongues are locked into the locking areas at a desired axial height.
  • the securing clips are held captively on clip guides of the fastening frame and can be actuated by the user by pressing radially inwards on an operating surface of the securing clips that functions as an actuation interface and moving the securing clips axially between an assembly position that unlocks the locking connections and a securing position that locks the locking connections, which is facilitated by a knurling on the operating surface facing radially outwards that prevents slipping.
  • the functional surface body is formed in several parts by a fastening surface on a head part of a plurality of holding feet, which can be inserted with a foot part into receiving openings on the outer circumference of the base section of the box housing body, preferably in corner areas thereof, and fixed at different axial heights, so that the box housing body or the connection box unit can be fixed to a building-side wall using these fastening surfaces.
  • the insertion of the holding feet into the receiving openings can be designed to snap into place.
  • a fixing clip is releasably inserted radially from the outside into suitable grooves in the holding feet.
  • the receiving openings function as a connecting structure with which the foot parts of the holding feet and the fixing clamps interact as connecting bodies, wherein the radially outer side of the fixing clamps functions as an actuation interface at which the respective fixing clamp can be gripped by the user in order to move it between its unlocking release position and its locking fixing position in the radial direction.
  • the invention is based on the technical problem of providing a wall-mounted connection box unit of the type mentioned at the outset, which offers, in particular, functional advantages and/or advantages with regard to manufacturing and/or assembly effort compared to the above-mentioned prior art.
  • the invention solves this problem by providing a wall-mounted connection box unit with the features of claim 1.
  • Advantageous developments of the invention are specified in the subclaims, the wording of which is hereby made part of the description by reference. This includes in particular all embodiments of the invention that result from the combinations of features that are defined by the references in the subclaims.
  • the connecting body is rotatable between the release position and the fixing position.
  • this represents an advantageous type of movement for the connecting body for corresponding applications.
  • the rotatable mobility can be achieved for the connecting body with comparatively little manufacturing effort and little space requirement and also requires relatively little accessibility space for the user to move the connecting body between its release position and its fixing position.
  • the connecting body can be rotated by the user without tools or using a turning tool with little space requirement from the side of the functional surface body facing away from the base section of the box housing body.
  • the actuation interface of the connecting body is located on a side of the functional surface body facing away from the base section of the box housing body. This advantageously enables the user to actuate the connecting body and thus the connecting device on the side of the functional surface body facing away from the base section in order to fasten the functional surface body to the base section and, if necessary, to release it again or to fix it at a different axial height on the base section.
  • the functional surface body is relatively easy for the user to access in typical applications of the connection box unit in order to move the connecting body between its release position and its fixing position.
  • this side of the functional surface body is usually still accessible to the user after the connection box unit has already been inserted into a wall opening on the building side or arranged on a wall on the building side.
  • This enables the user, for example, to axially adjust the height of the box housing body relative to a building wall even if the box housing body has already been arranged on the building wall or attached to it via the functional surface body.
  • Another advantage is that the base section of the box housing body does not get in the way of the user actuating the connecting body via the actuation interface, since the base section on the one hand and the actuation interface on the other hand are located on opposite sides of the functional surface body.
  • the connecting device is configured for selectively detachably fixing the functional surface body in front of a front or behind a rear of the base section of the box housing body.
  • This advantageously makes it possible to arrange the functional surface body optionally in front of the front or behind the rear of the base section of the box housing body and to hold it in this position on the base section.
  • This further increases the flexibility with regard to the possible uses of the functional surface body for providing, for example, a fastening surface or a sealing surface in selectable different axial positions relative to the base section.
  • This also applies in particular to the possibility of arranging the connection box unit in different axial positions in or on a building-side wall and installing it in or on it.
  • the at least one connecting structure is formed by a connecting structure element arranged in the base section of the box housing body.
  • the connecting structure is specifically provided by the connecting structure element in the base section, so that the base section can otherwise be kept free of the connecting structure.
  • the connecting structure can be formed by a Connecting structure element can be provided or can be formed without such a connecting structure element, e.g. directly on the base section itself.
  • the connecting structure element includes a sleeve element that extends continuously through the base section between a front side and a back side of the base section. This represents a manufacturing-technically and functionally advantageous implementation for the connecting structure element arranged in the base section of the box housing body.
  • connection structure element as a sleeve element can be easily combined with a rotatable design of the connecting body and/or with accessibility of the connecting body from the side of the functional surface body facing away from the base section. Since the sleeve element extends through the base section between its front and back, this implementation of the connecting structure element also creates a favorable prerequisite for a design of the connecting device in such a way that the functional surface body can be secured to the base section either in front of the front or behind the back of the base section. In alternative designs, a different connecting structure element is used, e.g.
  • a sleeve element that extends only from the front or the back into the base section, but not through it, or a similar element that is only open on one side and forms a type of blind hole opening, with which the functional surface body is secured to the base section only from the front or only from the back of the base section, or a fastening eyelet molded onto or attached to the base section or a snap-on area formed on the base section.
  • the at least one connecting structure includes a bolt receiving opening with an opening edge having a locking profile
  • the connecting body has a connecting bolt that can be inserted into the bolt receiving opening and rotated in the bolt receiving opening between the release position and the fixing position, which has a counter-locking profile on the circumference, wherein the locking profile and the counter-locking profile cooperate in a locking manner in the fixing position of the connecting bolt against axial movement of the connecting bolt out of the bolt receiving opening and in the release position of the connecting bolt allows the connecting bolt to move axially out of the bolt receiving opening.
  • connection device for releasably securing the functional surface body to the base section of the box housing body for numerous applications of the connection box unit.
  • a snap-in connection is used for this purpose, which can be snapped and locked in the bolt receiving opening or unlocked and disengaged again by turning the connecting bolt inserted axially into the bolt receiving opening.
  • the connection device is implemented by another conventional snap-in connection or another connection, such as a screw connection.
  • the actuation interface of the connecting body includes a front-side tool interface of the connecting bolt. This allows the connecting bolt to be rotated on its relevant front side using a corresponding turning tool between its release position and its fixing position.
  • the actuation interface is implemented in a different way, e.g. for direct user actuation without a tool interface or by means of a tool interface on the circumference of the bolt.
  • the locking profile includes one or more axially spaced locking webs, each of which extends within a locking web circumferential sector of the bolt receiving opening
  • the counter locking profile includes one or more axially spaced counter locking webs, each of which extends within a counter locking web circumferential sector.
  • only the locking profile outside the locking web circumferential sector or only the counter-locking profile outside the counter-locking web circumferential sector or both the locking profile outside the locking web circumferential sector and the counter-locking profile outside the counter-locking web circumferential sector contain at least one locking web within a locking web circumferential sector.
  • no axial locking or pre-fixing is provided or such is implemented by other means, e.g. in the form of a magnetic pre-fixing, which holds the connecting bolt pre-fixed in the bolt receiving opening at different axial heights by means of an appropriately configured magnet arrangement.
  • the sanitary wall-mounted connection box unit includes a loss prevention device that keeps the connecting body pre-assembled to the functional surface body in a loss-proof manner. This allows the connecting body to be pre-assembled to the functional surface body without being lost before the functional surface body is then secured to the base section of the box housing body using the connecting body.
  • the connecting body is provided separately and only arranged on the functional surface body when it is secured to the base section of the box housing body.
  • the wall-mounted connection box unit includes an end position latch that latches the connecting body in the fixed position onto the functional surface body so that it can be released. This latch can prevent the connecting body from being accidentally moved out of its end position corresponding to the fixed position.
  • the connection box unit does not have such an end position latch for the connecting body.
  • the wall-mounted connection box unit contains an anti-twist device, which has corresponding end position stops on the connecting body on the one hand and on the functional surface body or on the connecting structure on the other hand. These corresponding end position stops prevent accidental or undesired further rotation of the connecting body relative to the functional surface body and the connecting structure beyond the fixing position or the release position of the connecting body if this connecting body movement is a rotary movement.
  • an anti-twist device is missing.
  • the functional surface body includes a closed ring body with a sleeve section through-opening and at least one connecting body through-opening.
  • the functional surface body is particularly suitable for providing a functional surface extending radially around the sleeve section of the box housing body, such as a fastening ring surface and/or a sealing ring surface.
  • the functional surface body can be pushed onto the sleeve section of the box housing body, with the sleeve section passing through the associated through-opening, and the connecting body or bodies can be passed through the associated connecting body through-opening of the functional surface body for interaction with the connecting structure.
